' new and vuseful improvements in Drying Apparatus for Stamps, Labels, or Sealing- Strips, of which the following is a specification.

My present invention pertains to an improveddrying apparatus :tor stamps, labels,

`or sealing strips employed in conpmction with packaged materials. In the application of such articles to packages which are usually :tolded or closed in at'the end, ditliculty is experienced, by reason of the tact thatl the stamp, label or the like will become loose and, it such stamp be depended upon to hold the package closed or sealed, the package will open or be readily accessible.

The'main object of the present invention is to provide means for holding the stamp in position until the paste or other adhesive which is employed to secure it in place is fully set or dry and, at the same time, to provide a structure whichlivill readily periit the stamped packages to be ted there,- through as t-hey are delivered from a packaging machine.

A further object ot the inventionpis to so construct the mechanism -that a minimum amount ot drag will be exerted upon the stamps as thc stamped packages are passed through the machine, and .also to permit those portions of the mechanism which are liable to become coated or clogged with adhesive to he quickly withdrawn and as quickly replaced by a clean substitute part.

Vith these and other 'objects in view, a description of tlle invention will be given, reference beingghad to the annexed drawings, wherein:

Figure l is aside elevation of the mechanism; Fig. 2 a transverse sectional view, on t-he line QMQ of Fig. l; Fig. 3 an elevation of the packagedelivering mechanism and vone ot the transfer hunters; Fig. a a top plan view of the mechanism as a whole; Fig. 5 a perspective v iew ot one of the roll-carrying frames which form vthe upper portion of the runway for the packages when they are being moved through the machine .be-

vwhich wipe the ends of the stamps tween the drying plates; and Fig. G a pei spective view of one ot the drying and pressing plates.

The mechanism shown in the drawings and herein described is designed especially tor use in conjunction with a weighing and packaging machine, such as is illustrated in my copending application Serial No. 506,579 led on or about the 8th day ot July,'-'l90). It may, however, be used in connection with any other machine in which a stamp, label or strip is applied and held by an adhesive.

In the drawings, l denotes the completed package and 2 the stamp, which has been applied to the upper infolded end thereof, the ends of the stamp extending down the sides of the package, as best showniin Fig. 1. The term stamp will hereinafter be cmployed, though it will be understood as being the equivalent of a label, sealing-strip or the like.

The package is" brought to the position shown in Fig. 3 between the elevator or bunter 3 and the stamp-holder il, said holder in the present instance being shown as provii'led with a series ot rollers 5 in its under tace, which bear upon the previously-positioned stamp. The stamp to which the adhesive is applied is, prior to. being brought to the position shown, drawn over the upper end of the package and then moved upward by the elevator 3 between suitable devices down over the side edges of the package. lVhen the stamped package reaches the position shown in Fig. 3 bunter (i. nuivcs the saine laterally onto a table T, preferably provided with a planished metallic face or plate S. .fis the package travels onto the table it likewise passes beneath a series ot rollers 9, carried in a frame lO, which is removably mounted in a bracket ll. The elevator and stamp-holder, after the bunt-er G is withdrawn, move downwardly to bring another package to place. The bunter (3 carries the package to the position shown in Fig. El, in line. with a bunter or pusher l2, which works at right angles to the bunter 6 and in line with the table 7. The pusher 12 comes-into action after bunter G has been witlidrawn, and acts to advance the package along the table beneath a series of rollers 13, mounted and to be pin-jointed thereto.

A10 and both ol said frames are readily removable from their supports, so that others may be substituted in their place as occasion requires or when the rollers become sticky or gunnned by adhesive which exudes from beneath the stamps.

Secured to the upper face of the rails or -bars 1G and 17 and extending to each side thereof is a pair of brackets 22 and 2l-3, the ends of the brackets being bit'urcated and adapted todforin the supports for the levers or arms whichcarry and actuate the drying and pressing plates, of which there are two, one adapted to actV upon one end of the stamp and the other upon the opposite end as the packages are moved along the table. Each plate comprises an elongated metallic casting 2st, the inner face of which is perfectly smooth, and the extremity adjacent to the receiving end of the table is inclined or beveled downwardly, as at 25. The plate in the form illustrated is provided with a pair of lugs 2G and 27, adapted to receive and hold a gas-pipe 28, provided with a series ot' openings 2t), directed toward the plate. A cover-platetl,having inturned ends 31, is hinged to the upper flange of the plate let, the lower portion of said coverplate lying against the pipe, as shown in Fig. 2, thereby forming a substantially closed chamber which contines the heat against the presser-plate 24. Any form of heater may be employed, as for instance, an electric heater, which in practice has been successfully used. Each plate 2e is provided with a hinge lug 32 adapted to pass between the bit'urcated ends of bracket 2.

lever H3 also extends upwardly t'roin the plate adjacent to its beveled end, said lever being lornied withran opening lll through which a pin may be passed to secure the hinge joint and lever to the bracket The oppositely-disposed levers ot' the plates, which .tor the sake ol rlrarness are designated by -l and itil, are connected to cach other through a coil spring 35, secured to the upper ends of the levers, said spring tending to draw said ends together and consequently to throw the drying and pressing plates 2l outwardly or away l'roni each other. 'lo mme said plates inwardly or into position where they will contact with and press against the stamp ends, the following :forth is repeated;

noreste mechanism is employed: Secured to lever is an inwardlyextending arm 36 carryn ing at its outer end an adjustable screw 3T, the lower end of the screw contacting with the outer end of an arm 38 secured to lever 33j Swiveled upon the upper end or" Alever is a yoke 39, connected through an time moviles,` the pressing' and drying plate to which the lever 33 is attached outwardly. prinp; 3o beingt under stress will rock lever 33 and consequently throw its plate outwardly sii'nultaneously with the outwardinovement of the opposite plate. A reverse movement of lever 42 will throw arm 3S upward and, through screw 37, 'aise arm 36 and torce the upper end of lever 33'out wardly, thereby swinging its plate inwardly into pressingposition as the opposite plate is brought into like relation. l t will thus' be seen that the plates are opened and closed simultaneously and by adjust-ingthe link 40 and the screw 37 may be made to exert-the desired degree of pressure upon the stamp.

The various parts, such as'the elevator, hunters and presser-plates, are all timed to work in their proper sequence, so that while a package is being brought to position by the elevator 3 the hot or warin presser plates will. be momentarily opened or separated, and pusher 12 will advance and move the previously-deposited packagesalong the table 7 a distance equal to the'thickness of one package, or slightly more. When this is aceon'iplisl-ied, vthe pusher is moved away and.

the presser plates close in upon the stamp ends. p While these members are' at rest, bunter t3 advances a packageljust positioned by the elevator or lifter l from beneath rollers 5 to and beneath rollers l) in -front of the pusher 12. Bunter (5 is then retracted and.

the same cycle of operations as above setl l d -lt will be noted from the lforegoing de scription that the stamp, or at least the upper or central poi-tion thereof, is constantly held under rollers and this does away with any drag on the stamp and consequent misblacenient thereof. Furthermore, as the package is moved along the table, the ends of the stamps, ill they should become curled mitwardly, will eomein Contact with the beveled ends and be smoothed down against the package As willlbe seen upon 145, the ends aga reference to Fig. G, the upper portion of the beveled edge 2o will contact with the stamp nearestI the upper portion of the package, and as the package is moved inwardly along 5 said edge the downward inclination ot the edge will tend to d aw or wipethe stamp.

chance for the stamps to curl as the plat-es.l

are only separated momentarily. By the time the packages have passed from betweentheplates. the stamps will be perfectly dry or the adhesive set to such a degree as to firmly hold the stamp in place.

By having` the 'roll-carrying trames readily removable a. iclean set oit rolls" may he quickly substituted for a .set which may have become sticky or gummed from the exuding adhesive. 1

As above noted, the herein and in the appended claims is to be .treated as a generic term.
